Is this coworker actually interested in me or just being friendly?

This girl has rarely joined my convos in the past and I never said much to her til now. At a bar she was having a discussion about if she wanted kids or not. She said no and then the discussion kept going on and later she said “i think i just wanna be on my own”. not sure if she meant she doesn’t want a boyfriend or doesn’t want a kid. once the whole party was done we all were saying goodbye to each other but we didn’t even say bye to each other at all like everyone else did.

It’s probably bc i barely know her though. she would join in convos sometimes and she would hold eye contact when talking to me. She did laugh and engage too when i spoke. Sometimes she was standing next to me too. Next day we didn’t say hi to each other but later I was making a joke with a coworker by saying “super big” in an out of context way. she came in and heard it and said “what’s going on here” after like 6 seconds of when my joke was said. I said “don’t worry about it jokingly she just gave me eye contact/smiled. Next day I was asking my coworker what was “green goddess” and then she comes in and says “you don’t know what green goddess is?” while smiling then we had a short convo.

Later I accidentally kept getting in her way and I said “oh shit” & she just laughed. Later i accidentally dropped glass on the floor, she asked me what happened. Few mins later she almost fell and said how she doesn’t want to fall. I assumed she was talkikg about the glass so i said ill make space for her and she said “oh no i was going to fall before getting there” & that it was bc she doesn’t have her slip shoes. I then asked why and she gave me a reason. she also commented on how im one of the only good (my job role) at the job.
